New Zealand has broadcast the Islamic call to prayer and observed a two-minute silence in ceremonies to mark a week since the Christchurch attacks.
Prime Minister Jacinda Ardern joined thousands of mourners near the Al-Noor mosque, one of two places of worship targeted in last Friday's shootings.
Addressing the Muslim community she said: "New Zealand mourns with you, we are one."
Fifty people were killed and dozens more wounded in the attacks.
Australian Brenton Tarrant, a self-proclaimed white supremacist, has been charged with one murder and is expected to face further charges.
On Thursday Ms Ardern announced a ban on all types of semi-automatic weapons.
What is happening on Friday?
Thousands of people have gathered in Hagley Park, near the Al-Noor mosque, to mark Friday's national day of reflection for the victims.
The Muslim call to prayer, or adhan, was broadcast on national television and radio at 13:30 (00:30 GMT) and was followed by a two-minute silence.
In an address beforehand, Ms Ardern said: "According to the Prophet Muhammad... the believers in their mutual kindness, compassion and sympathy are just like one body. When any part of the body suffers, the whole body feels pain."
